The dash_write function drops data, if no IOContext is initialized. Since the mp4 muxer is used in "frag_custom" mode, data is only written when calling av_write_frame(NULL) explicitly and thus there will be no data loss. To add support for webm as subordinate muxer, which doesn't have such a mode, a dynamic buffer is required to provide an always initialized IOContext.
